expand 1/((s+a)*(s+b)^2)

expand

\frac{1}{( s + a ) \cdot ( s + b ) ^{2}}

\frac{1}{s ^{3} + 2 b s ^{2} + b ^{2} s + a s ^{2} + 2 ab s + a b ^{2}}

Solution steps

\frac{1}{( s + a ) ( s + b ) ^{2}}

(s + b)^{2} = s^{2} + 2 b s + b^{2}

= \frac{1}{( s + a ) ( s ^{2} + 2 b s + b ^{2} )}

Expand

(s + a) (s^{2} + 2 s b + b^{2}) : s^{3} + 2 b s^{2} + b^{2} s + a s^{2} + 2 ab s + a b^{2}

= \frac{1}{s ^{3} + 2 b s ^{2} + b ^{2} s + a s ^{2} + 2 ab s + a b ^{2}}

\frac{1}{5 ( x + 1 )}

(2 n + 1) π - \frac{π}{2}

(3 a^{2} c) 3

(2 T - 1) (π + 5)

(\frac{5 π}{12} - \frac{1}{4}) 100
